FIELD OF THE INVENTION

This invention relates generally to novel hydantoin derivatives that caninhibit matrix metalloproteinases (MMPs), a disintegrin andmetalloproteases (ADAMs) and/or tumor necrosis factor alpha—convertingenzyme (TACE) and in so doing prevent the release of tumor necrosisfactor alpha (TNF-α), pharmaceutical compositions comprising suchcompounds, and methods of treatment using such compounds.

BACKGROUND OF THE INVENTION

Osteo- and rheumatoid arthritis (OA and RA, respectively) aredestructive diseases of articular cartilage characterized by localizederosion of the cartilage surface. Findings have shown that articularcartilage from the femoral heads of patients with OA, for example, had areduced incorporation of radiolabeled sulfate over controls, suggestingthat there must be an enhanced rate of cartilage degradation in OA(Mankin et al. J. Bone Joint Surg. 52A (1970) 424-434). There are fourclasses of protein degradative enzymes in mammalian cells: serine,cysteine, aspartic and metalloproteases. The available evidence supportsthe belief that it is the metalloproteases that are responsible for thedegradation of the extracellular matrix of articullar cartilage in OAand RA. Increased activities of collagenases and stromelysin have beenfound in OA cartilage and the activity correlates with severity of thelesion (Mankin et al. Arthritis Rheum. 21, 1978, 761-766, Woessner etal. Arthritis Rheum. 26, 1983, 63-68 and Ibid. 27, 1984, 305-312). Inaddition, aggrecanase (a newly identified metalloprotease) has beenidentified that provides the specific cleavage product of proteoglycan,found in RA and OA patients (Lohmander L. S. et al. Arthritis Rheum. 36,1993, 1214-22).

Metalloproteases (MPs) have been implicated as the key enzymes in thedestruction of mammalian cartilage and bone. It can be expected that thepathogenesis of such diseases can be modified in a beneficial manner bythe administration of MP inhibitors (see Wahl et al. Ann. Rep. Med.Chem. 25, 175-184, AP, San Diego, 1990).

MMPs are a family of over 20 different enzymes that are involved in avariety of biological processes important in the uncontrolled breakdownof connective tissue, including proteoglycan and collagen, leading toresorption of the extracellular matrix. This is a feature of manypathological conditions, such as RA and OA, corneal, epidermal orgastric ulceration; tumor metastasis or invasion; periodontal diseaseand bone disease. Normally these catabolic enzymes are tightly regulatedat the level of their synthesis as well as at their level ofextracellular activity through the action of specific inhibitors, suchas alpha-2-macroglobulins and TIMPs (tissue inhibitor of MPs), whichform inactive complexes with the MMP's.

Tumor necrosis factor alpha (TNF-α) is a cell-associated cytokine thatis processed from a 26 kDa precursor form to a 17 kd active form. SeeBlack R. A. “Tumor necrosis factor-alpha converting enzyme” Int JBiochem Cell Biol. 2002 January; 34(1):1-5 and Moss M L, White J M,Lambert M H, Andrews R C. “TACE and other ADAM proteases as targets fordrug discovery” Drug Discov Today. 2001 Apr. 1; 6(8):417-426, each ofwhich is incorporated by reference herein.

TNF-α has been shown to play a pivotal role in immune and inflammatoryresponses. Inappropriate or over-expression of TNF-α is a hallmark of anumber of diseases, including RA, Crohn's disease, multiple sclerosis,psoriasis and sepsis. Inhibition of TNF-α production has been shown tobe beneficial in many preclinical models of inflammatory disease, makinginhibition of TNF-α production or signaling an appealing target for thedevelopment of novel anti-inflammatory drugs.

TNF-α is a primary mediator in humans and animals of inflammation, feverand acute phase responses, similar to those observed during acuteinfection and shock. Excess TNF-α has been shown to be lethal. Blockingthe effects of TNF-α with specific antibodies can be beneficial in avariety of conditions, including autoimmune diseases such as RA (Feldmanet al, Lancet, (1994) 344, 1105), non-insulin dependent diabetesmellitus (Lohmander L. S. et al., Arthritis Rheum. 36 (1993) 1214-22)and Crohn's disease (Macdonald T. et al., Clin. Exp. Immunol. 81 (1990)301).

Compounds that inhibit the production of TNF-α are therefore oftherapeutic importance for the treatment of inflammatory disorders.Recently it has been shown that metalloproteases, such as TACE, arecapable of converting TNF-αfrom its inactive to active form (Gearing etal Nature, 1994, 370, 555). Since excessive TNF-α production has beennoted in several disease conditions also characterized by MMP-mediatedtissue degradation, compounds which inhibit both MMPs and TNF-αproduction may also have a particular advantage in diseases where bothmechanisms are involved.

One approach to inhibiting the harmful effects of TNF-α is to inhibitthe enzyme, TACE before it can process TNF-α to its soluble form. TACEis a member of the ADAM family of type I membrane proteins and mediatesthe ectodomain shedding of various membrane-anchored signaling andadhesion proteins. TACE has become increasingly important in the studyof several diseases, including inflammatory disease, because of its rolein cleaving TNF-α from its “stalk” sequence and thus releasing thesoluble form of the TNF-α protein (Black R. A. Int J Biochem Cell Biol.2002 34, 1-5).

U.S. Pat. No. 6,495,565 discloses lactam derivatives that are potentialinhibitors of MMPs and/or TNF-α.

PCT Publications WO2004024698 and WO2004024715 disclose sulphonamidederivatives that are potential inhibitors of MMPs.

PCT Publications WO2004056766, WO2003053940 and WO2003053941 alsodescribe potential inhibitors of TACE and MMPs.

There is a need in the art for inhibitors of MMPs, ADAMs, TACE, andTNF-α, which can be useful as anti-inflammatory compounds and cartilageprotecting therapeutics. The inhibition of TNF-α, TACE and or other MMPscan prevent the degradation of cartilage by these enzymes, therebyalleviating the pathological conditions of OA and RA as well as manyother auto-immune diseases.

Example 4100

Compound 4100C was prepared from compound 4100A and commerciallyavailable Compound 4100B by procedures given in Example 14 and 1009.Subsequently, compound 4100C (123 mg, 0.2 mmol) was dissolved inmethanol (1 mL) in a pressure tube and treated with HCl (0.4 mL, 4 M indioxane). The tube was sealed and heated with stirring at 90° C. for 18h. The reaction mixture was allowed to cool to rt and the solvent wasthen removed under reduced pressure. The residue was re-dissolved inmethanol (1 mL) and DIPEA (0.27 mL, 0.20 mg, 1.6 mmol) was added. Thereaction mixture was stirred overnight at rt. The volatile componentswere removed by evaporation and the residue was purified by PTLC (8%MeOH—CH₂Cl₂) to give Compound 4017 (59 mg, 61% yield) as a beige solid.

Example 1022

Step 1

To a solution of 1022A (500 mg, 3.33 mmol) in acetone (40 mL) were addedpotassium carbonate (920 mg, 6.7 mmol) and 1-bromo-2-butyne (0.32 mL,3.7 mmol, in case of R═CH₂CCCH₃). The reaction mixture was heated toreflux for 2 h. After cooling to RT, the mixture was added to icewater/CH₂Cl₂. The organic layers were extracted with CH₂Cl₂ and thecombined organic solution was washed with saturated aqueous NaClsolution, dried (Na₂SO₄), and concentrated in vacuo to afford 1022B (674mg, quantitative yield).

Steps 2 and 3

A suspension of 1022B (100 mg, 0.5 mmol) in 1N NaOH solution (0.5 mL)was heated to 100° C. The reaction mixture was stirred for 1 h at thetemperature and concentrated in vacuo. The residue was dried byazeotropic distillation with toluene and the resulting solid wasdissolved in DMF (0.6 mL) followed by addition of xs. MeI (0.1 mL, 1.5mmol). The mixture was stirred at RT for 2 h and diluted in EtOAc. Theorganic solution was washed with water, saturated aqueous NaCl solution,dried (Na₂SO₄), and concentrated in vacuo to give crude 1022C (117 mg).The crude 1022C (67 mg, 0.28 mmol) was dissolved in CH₂Cl₂ (2 mL) andthe solution was treated with PPh₃ (150 mg, 0.57 mmol) and CBr₄ (189 mg,0.57 mmol) at RT. The mixture was stirred at RT for 1 h and concentratedin vacuo. The residue was purified by preparative TLC (CH₂Cl₂) to afford1022D (50 mg, 60% yield).

Example 1023

Step 1

A mixture of 1023A (370 mg, 0.72 mmol),1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole(225 mg, 1.08 mmol), potassium carbonate (1M aqueous solution, 2.9 mL,2.9 mmol), and [PdCl₂(dppf)]CH₂Cl₂ (59 mg, 0.072 mmol) in acetonitrile(12 mL) was vacuumed and refilled with argon three times. The reactionmixture was stirred at 80° C. oil bath for 17 hours. After cooling down,the mixture was diluted in EtOAc (50 mL) and filtered through a celitepad. The filtrate was concentrated in vacuo and the residual materialwas purified by silica gel column chromatography (1% to 1.5% MeOH inCH₂Cl₂) to afford compound 1023B (369 mg, 99% yield).

Step 2

A solution of 1023B (109 mg, 0.21 mmol) in EtOAc/MeOH (4/1, 5 mL) wastreated with 4N HCl in dioxane (2 mL). The reaction mixture was stirredat RT for 15 h and concentrated in vacuo.
